If the network server fails to load a configuration file during startup, it
tries again every 10minutes (the default setting) until a host provides
the requested files. With each failed attempt, the network server dis-
plays a message on the console terminal. If the network server is un
able to load the specified file, it displays this message:
Booting host-confg... [timed out]
If there are any problems with the startup configuration file, or if th
configuration register is set to ignore NVRAM, the router enters the
setup command facility. Refer to Use Setup for Configuration
Change , for details on the setup command.
Store System Images and Configuration Files
After modifying and saving your routing environment's u nique config-
urations, you might want to store them on a network server. You can
use these network server copies of system images and configuration
files as backup copies.

Store System Images and Configuration Files Task List

To store system images and configuration files:
zCopy System Images from Flash Memo ry to a Network Server
zCopy Configuration Files from the Router to a Network Server

Copy System Images from Flash Memory to a Network

Server

You can copy system images from Flash memory to a TFTP server.
You can use this server copy of the system image as a backup copy, or
you can use it to verify that the copy in Flash is the same as the original
file on disk.
In some implementations of TFTP, you must first create a "dummy"
file on the TFTP server and give it read, write, and execute permis-
sions before copying a file over it. Refer to your TFTP documentation
for more information.
To copy a system image to a TFTP network server, perform these tasks
in EXEC mode:

of the system image filename in Flash memory.
